Chronicle of Polyphony

After each Miliastra Pass event begins, rewards in Chronicles of the Skies will be unlocked by default. Travelers can also unlock Chronicles of the Realms or Epic of the Realms to obtain more generous rewards. Travelers who have already unlocked Chronicles of the Realms need only exchange the remaining difference in cost through purchasing Chronicle Recompilation in order to unlock Epic of the Realms. The purchase of Chronicles of the Realms, Epic of the Realms, and Chronicle Recompilation for this Miliastra Pass period will be available until 2026/05/18. After the purchase period ends, you can still complete Chronicle Missions and claim rewards. Traveler, please take note of the purchase period and event duration of the Miliastra Pass. After unlocking "Chronicles of the Realms" or "Epic of the Realms," you will unlock the Battle Pass Boon effect, granting a discount when purchasing the corresponding Battle Pass in Teyvat. Likewise, unlocking "Gnostic Hymn" or "Gnostic Chorus" will grant the Chronicle Boon effect, offering a discount when purchasing the corresponding Miliastra Pass in Miliastra Wonderland. You can check the Boon button on the Miliastra Pass or Battle Pass purchase screen for more details. The Boon effect can only be activated once during the current event period. The Miliastra Pass and Battle Pass share the same start and end dates each period. Please be sure to check the time and claim your rewards promptly.
